FASTENING DEVICE.

Application `11ed October S, 1918.

To all whom t may concern.'

Be it known that I, GEORGE S. SOLOMON, a citizen of the United States, and a resident of Bisbee, in the county of Cochise and State of Arizona, have invented a new and Improved Fastening Device, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved fastening device more especially designed for securely and quickly fastening fence posts, telegraph posts telephone posts and other posts to foundations such as concrete blocks. Another object is to insure a tight joint between the bottom of the post and the top of the foundation. Another object is to permit removing the post from the foundation whenever it is desired to do so and without disturbing the foundation block.

With these and other objects in view, the invention consists of certain novel features of construction, as hereinafter shown and. described and then specifically pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying draw* ings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of a post attached to a concrete foundation block by the use of the improved fastening` device;

Fig. 2 is a sectional side elevation of the same on the linel 2-2 of Fig. 1;

Fig. 3 is a sectional plan view of the same on the line 3 3 of Fig. 2; and

Fig. 4; is a side elevation of the foundation nipple.

The fastening device as illustrated in the drawings is used for fastening a post 10 to a foundation in the form of a concrete block 11 set in the ground 12. The fastening device comprises a sleeve 15 having a lower portion 16 mounted to turn in a recess 17 formed in the top of the foundation block 11 and the said sleeve 15 has its upper portion 18 mounted to turn in a recess 19 formed in the bottom of the post 10. The upper and lower portions 18 and 16 of the sleeve are provided with interior screw threads of which one is right-handed and the other left-handed. The lower portion 16 of the sleeve 15 screws on the upper threaded end of a foundation nipple 20 en Specification of Letters Patent.

tending in a bore 21 formed in the foundation 11 concentrically with the recess 17. The lower end of the nipple 20 is provided with a bayonet slot 22 adapted to be engaged with a locking pin 23 held in the foundation block 11 to prevent the nipple 20 from turning and from being lifted out of the foundation block 11. Into the upper portion 18 of the sleeve 15 screws the lower end of a post nipple 25 extending in a bore 26 formed in the post 10 concentric with the recess 19. rlhrough the upperV end of the nipple 25 extends transversely a pin 27 held in the post 10 to prevent the nipple 25 from turning in the post.. Y

The sleeve 15 is provided with an external polygonal portion 30 intermediate the lower and upper portions 16 and 18, and this polygonal portion 30 is engaged by a correspondingly shaped aperture 31 formed in a plate 32, preferably in the form of a disk larger in diameter than that of the lower end ofthe post 10 .to project beyond the same. The projecting portion of the plate 32 is provided with spaced apertures 33 adapted to be engaged by a spanner wrench or a similar tool to permit of turning the plate 32 with a view to screw the sleeve 15 onto the threaded ends of the nipples 20 and 25.

in using the fastening device the nipples 20 and 25 are screwed into the sleeve 15 and the nipple 25 is then placed in position in the post 10 and fastened therein by the pin 27. The post 10 in erectposition is now moved over the foundation block 11 and lowered to pass the foundation nipple 2O into the bore 21 to engage the bayonet slot 22 with the locking pin 23. A quarter turn is then Igiven to the post to engage the angular portion of the bayonet slot with the locking pin thus holding the nipple 20 against turning or lifting it out ofthe bore 21. The Operator now turns the plate 32 by the use of a suitable tool to turn the 100 sleeve 15 and thereby screw the nipple home and draw the post downward into firm engagement with the plate 32. It will be noticed that by the arrangement described a very tight joint is formed between the top 105 of the foundation block 11, the bottom of the post 10 and the plate 32 used for turning the sleeve 15. as above explained. It will also be noticed that the members of the fastening device except the plate 32 are 110 completely out of sight and are not liable to be affected by nioisture or other deleterious external influences. v

The fastening device shown and described is very simple and durable in construction and permits of quickly and seeurely fastening a post in position on a suitable foundation, preferably in the nature of a concrete block, as above described and shown in the drawings. lf desired, the post can be readily removed froni the foundation block without disturbing the foundation block in the ground.

Having thus described iny invention, I claini as new and desire to secure by Letters Patent:

l. A, fastening device for fastening a post to a concrete foundation, comprising a sleeve having its upper portion extending centrally into the bottoni of the post and. having its lower portion extending into the top, of the foundation, the said top and bottom portions of the sleeve having interior right and left hand threads, a foundation nipple screwed into the lower portion of the sleeve and adapted tov be locked in place in the said foundation block, and a post nipple held against turning and screwing into the upper portion of the said sleeve.

A fastening device for fastening a post to a concrete foundation comprising a sleeve having vits upper portion extending centrally into the bottoni of the post and having its lower portion extending into, the top ofthe foundation, the said top and bottoni portions of the sleeve having interior right and left lmnd threads, the said sleeve having a` polygonal exterior portion intermediate its ends, a plate having a polygonal aperture engaged by the said polygonal portion of the sleeve, the said plate having ineans to permit of turning the plate to turn the sleeve, a foundation nipple screwed into the lower portion of the sleeve and adapted to be locked in place in the said foundation block, and a post nipple held aga-inst turning and screwing into the upper portion of the said sleeve.

3. A fastening device for fastening a post to a concrete foundation'comprisinga sleeve having a bottoni portion mounted to1 turn in the top of the said foundation and having a top portion adapted to turn in the bottom of the post, one of the said portions having a right-hand thread and the other having a left-hand thread, a foundation nipple having its upper end threaded and screwing into tov a concrete foundation, comprising a sleeve' having a bottoni portion mounted to turn in the top of the said foundation and having a top portion adapted to turn in thebottoni of the post, one of the said portions having a right-,hand thread and the other having a left-hand thread, a foundation nipple having its upper end threaded and screwing intoA the lower sleeve portion, the lower end of the said foundation ynipple having a Ybayonet slot, a locking pin held in the said founda tion block and engaging the said bayonet slot to Vlocl; the said foundation nipple in place. in they foundation block, a post nipple having its lower end threaded and screwing into the said upper sleeve. portion and a locking pin held in the pest and extending transversely through the. said post nipple to hol-d the latter against turning, the., latter having a polygonal portion intermediate its. top, and bottoni portions and; a plate having a pol-ygonal aperture engaged by the said polygonal sleeve portion, the said plate extending betweentthe. foundation block and the. post and projectingbeyond the peripheral face of the post,the said projecting portion of the plate having apertures for the` application of a tool forv turning the plate and with it the sleeve. Y
